Preparatory work to fix the user directory assuming that any remote membership state events represent a profile change. [rei:userdirpriv] (#14755)
* Remove special-case method for new memberships only, use more generic method

* Only collect profiles from state events in public rooms

* Add a table to track stale remote user profiles

* Add store methods to set and delete rows in this new table

* Mark remote profiles as stale when a member state event comes in to a private room

* Newsfile

Signed-off-by: Olivier Wilkinson (reivilibre) <oliverw@matrix.org>

* Simplify by removing Optionality of `event_id`

* Replace names and avatars with None if they're set to dodgy things

I think this makes more sense anyway.

* Move schema delta to 74 (I missed the boat?)

* Turns out these can be None after all
